In February '06, I decided to replace my carburetors on an '82 Yamaha XJ1100 Maxim motorcycle with an electronic fuel injection (EFI) system; and upgrade the ignition system. The results were amazing; my mileage when from 32 mpg to 44-47 mpg, the bike starts easier, and runs great. I built a website to document the project, Stanís XJ1100 Fuel Injection Project.
